The Portable Atheist concludes

The 47^th "essential reading for the nonbeliever" included in Christopher Hitchens's Portable Atheist is Ayaan Hirsi Ali's "specifically written essay on her decision to say farewell to all gods." And the following paragraphs are its (and the whole book's) concluding ones:

Now I told myself that we, as human individuals, are our own guides to good and evil. We must think for ourselves; we are responsible for our own morality. I arrived at the conclusion that I couldn't be honest with others unless I was honest with myself. I wanted to comply with the goals of religion—which are to be a better and more generous person—without suppressing my will and forcing it to obey an intricate and inhumanly detailed web of rules. I had lied many times in my life, but now, I told myself, that was over: I had had enough of lying.
    After I wrote my memoir, Infidel (published in the United States in 2007), I did a book tour in the United States. I found that interviewers from the Heartland often asked if I had considered adopting the message of Jesus Christ. The idea seems to be that I should shop for a better, more humane religion than Islam, rather than taking refuge in unbelief. A religion of talking serpents and heavenly gardens? I usually respond that I suffer from hayfever. The Christian take on Hellfire seems less dramatic than the Muslim version, which I grew up with, but Christian magical thinking appeals to me no more than my grandmother's angels and djins.
    The only position that leaves me with no cognitive dissonance is atheism. It is not a creed. Death is certain, replacing both the siren-song of Paradise and the dread of Hell. Life on this earth, with all its mystery and beauty and pain, is then to be lived far more intensely: we stumble and get up, we are sad, confident, insecure, feel loneliness and joy and love. There is nothing more; but I want nothing more. [pp. 479-480]

The point, though, is that, however much we might want more, we are not going to get it. An individual's project in facing la condition humain is as it has always been: Deal with it.
    I started to say that to deny the "nothing more" aspect of it (as religious indoctrination routinely programs children to do) is not to deal with it, but to avoid it. While in a purely semantic sense that is so, people "deal with" all sorts of things by simply avoiding them. If we aren't equipped to face up to something (and it takes a lot to be able to face up to the fact that we and all of our friends and relatives are going to die), what are we going to do? Many people party as much as possible—the "eat, drink, and be merry" approach...And others take shelter in the comforting myths of religion.
    Critical questioners like Ayaan Hirsi Ali find that they can't square that avoidance with the dicates of conscience and mental health.
